Motor commutator for constant directional torque

Update:14 Feb 2022

Since the motor commutator is an important part of the armature of the DC motor and the AC commutator, it is widely used in the motor. At the same time, it is a device that converts direct current into low frequency square wave to increase the power of the electrode and then converts the square wave signal measured by the measuring electrode into pulsating direct current.

When the commutator passes the current coil, it is under the action of the permanent magnet. After attraction and repulsion, the motor returns to a state of equilibrium and magnetism, corresponding to the original wire and electrical contact pieces left on the commutator, and to the brush set corresponding to the contact points of the steam coil match. The commutator repeats this action until the motor does not start.

At the same time, because it can change the AC potential in the component to the DC potential of the brush, and on the electrical side, it can convert the applied DC current into the AC current in the component, thereby generating a constant directional torque. Therefore, it is widely used in various types of motors.

In the daily processing process, the factory will choose to use different types of motors for daily processing. At the same time, the motor also contains a commutator produced by the commutator manufacturer, and the commutator can be defined as a rotary switch type generator at a specific point. Second, the brushes or electrical contacts are made of carbon pressed material close to the commutator, with sliding contact designed through successive sections of the commutator as the commutator rotates.

The commutator in a general motor is composed of a set of contact rods, and these contact rods are arranged on the rotating shaft of the DC motor and connected with the armature winding. When the shaft turns, the commutator will reverse the current in the windings. Second, for a particular armature winding, when the shaft completes half a turn. The windings are connected so that the current flows through it in the opposite direction.

At the same time, with the continuous progress and improvement of technology, the technology used in the commutator has also been improved accordingly. And the commutator can change the direction of the current in the bead by every half-turn, thereby generating torque. Therefore, it is widely used in various types of motors, and is well recognized by users.
